Description

Se agrega la opción de no TTY para CI

[danteay]

LGTM. Clean and well-scoped change.

What was reviewed:

• Refactoring of executeConcurrentWithProgress to decouple progress reporting from work logic via the runWork(onProgress) callback pattern.
• TTY vs non-TTY branching: spinner for interactive terminals, plain log output for CI.
• The isTTY() helper correctly delegates to data.Flags.TTY, which defaults to true in the CLI root command.

Positives:

• The callback-based approach (onProgress func(string)) is clean and avoids code duplication between TTY and non-TTY paths.
• Redundant comments were removed, improving readability.
• Change is backward-compatible (TTY defaults to true).

Minor note (non-blocking):

• No new tests for the TTY branching, but given the trivial nature of isTTY() and that the core work logic is shared, this is acceptable.

All CI checks pass. Approved.
